Pp. pertusum, . Roxaunen s MSS. ‘oui a Fouive: 
: aiite, scaly,’ creeping, throwing out several branched and 
; vny roots. Fronds erect, of a thick and fleshy substance, nerve- 
le 8; dark green above, and channelled in the centre, with a prominent 
) idrib beneath, thickened at the margin on both sides, beset with ex- 
> eee ingly minute, scattered, beautifully stellated scales, which are invi- 
- sible to the naked eye, at the base gradually tapering into glabrous, 
«grooved stipes, about an inch long: sterile fronds 2-4 inches in length, 
~~» oblong-lanceolate, obtuse ; fertile ones 6 inches long, linear-lanceolate. 
‘ructification produced at the back of the upper half of the frond, imbedded 
. in, and at first wholly concealed by, a dense whitish woolly mass, which 
covers the whole back of the frond as far as the fructification extends, 
and is composed of an infinite number of the same kind of stellated 
scales as are scattered so sparingly over the rest of the frond. Sori oval, 
consisting of about 8-12 spherical, pedicellated annulated capsules. 
Introduced from China by the Horticultural Society of 
London, and presented by that truly liberal institution to the | 
Botanic Garden of Liverpool, where it has flourished, and where 
it bore its singular fructification in the month of November. 
- Stellated scales are found upon not a few of the simple 
fronded Polypodia: in this individual, however, there is a | 
dense mass of them upon that portion of the frond which pro- 
duces the fructification; the clusters of capsules at first lie
